Got something you want to ask Edward Snowden? Maybe about his work at the National Security Agency or how he's getting along in Russia? Or perhaps something a bit less complimentary?

You might get your chance to pose such questions on Tuesday when Twitter CEO Jack Dorsey interviews the famed NSA whistleblower via video conference. The interview will be broadcast at 9:05 a.m. PT on Periscope,

Twitter's live-streaming app.

It's been three years since Snowden, now 33, leaked information about NSA surveillance programs like Prism, which gave the US access to people's emails, video chats, photos and documents through some of the world's biggest tech companies. The disclosures put pressure on Silicon Valley companies including Apple, Google and Yahoo to step up their efforts in encryption and privacy and galvanized the companies to push back against the government on issues of spying and user data.

The Q&A session was announced Monday by Pardon Snowden, a campaign launched in September by major civil rights groups working to win official forgiveness for Snowden. The former NSA-contractor-turned-whistleblower has been living in self-imposed exile in Russia to avoid the charges he faces in the US for violating the Espionage Act and other laws.

Edward Snowden is an American whistleblower who copied and leaked highly classified information from the National Security Agency in 2013 when he was a Central Intelligence Agency employee and subcontractor. His new book "Permanent Record" is now available.
